                    SUSE Linux Enterprise Live Patching 12-SP4
______________________________________________________________________________

   An update that fixes four vulnerabilities is now available.

Description:

   This update for the Linux Kernel 4.12.14-95_74 fixes several issues.

   The following security issues were fixed:

   - CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the
     netfilter subsystem. This vulnerability gives an attacker a powerful
     primitive that can be used to both read from and write to relative stack
     data, which can lead to arbitrary code execution. (bsc#1197335)
   - CVE-2022-1011: Fixed an use-after-free vulnerability which could allow a
     local attacker to retireve (partial) /etc/shadow hashes or any other
     data from filesystem when he can mount a FUSE filesystems. (bsc#1197344)
   - CVE-2021-39713: Fixed a race condition in the network scheduling
     subsystem which could lead to a use-after-free (bsc#1197211).
   - CVE-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP
     transformation code. This flaw allowed a local attacker with a normal
     user privilege to overwrite kernel heap objects and may cause a local
     privilege escalation. (bnc#1197133)
